观察力是人们探索和发现大自然奥秘的前提,是全面、深入认识客观世界,获取知识,发现问题的源泉。纵观古今中外众多的科学家、发明家,他们的发现、发明和创造无一不是基于实践,始于观察。化学实验,观察是第一步,没有观察,就没有接踵而来的前进。”因此在化学实验教学中,教师应首先抓住学生的观察力进行培养。要培养学生的观察能力必须经过教师的正确引导,使学生掌握要领,抓住本质,突出重点。
Observational force is the premise for people to explore and discover the mysteries of nature, and is the source of comprehensively and in-depth understanding of the objective world, access to knowledge and discovery of problems. Throughout the many ancient and modern scientists and inventors, their discoveries, inventions and creations are all based on practice and begin with observation. Chemical experiments, observation is the first step, there is no observation, there is no one after another. Therefore, in chemistry experiment teaching, teachers should first grasp students ’observation ability to cultivate.To train students’ observation ability must be guided by the teacher correctly, make the students grasp the essentials, grasp the essence, and give prominence to the key points.
